The New Measure for Dose Calibrators in Today’s Nuclear Medicine Environment

The new CRC®-25R Dose Calibrator gives you the state-of the-art technology, plus many outstanding new features in one small package. The CRC®-25R is designed to meet the demands of your Nuclear Medicine Department with accuracy and ease of operation unlike ever before. With added features including USB/PC Communications and printer capability, a SD flash card software upgrade, a chamber plug-and-play feature and expanded remote capabilities, the CRC®-25R will continue to prove to be an asset to your workplace.

The space efficient design of the CRC®-25R allows for a large, easy-to-read display that indicates Nuclide Name, Number, Activity, Unit of Measure and Calibration Number. A sophisticated microchip platform eliminates analog controls, while boosting speed of activity measurements.

All nuclide data is entered via the custom keyboard, that includes 8 preset and five user-definable keys. In addition, the user can enter in over 80 nuclides by using the Nuclide symbol such as Co for cobalt and 60 for Co 60. Calibration numbers for over 200 radionuclides are easily accessed by use of the Cal key.

Other capabilities include storage of five reference sources in memory that are automatically decay corrected for today’s time and date. Dose calibration quality control tests and self-diagnostics are built-in along with automatic zero and background subtraction making the CRC®-25R extremely easy to use. An optional printer enables the CRC®-25R to print full size records and patient tickets with peel off labels for vial and syringe identification.
